detect if a key was pressed in matlab

You can detect if a key was pressed in MATLAB using the waitforbuttonpress function. This function waits for either a mouse click or a keyboard key press. Here's an example:

main.m
disp('Press any key');
waitforbuttonpress; % Wait for key press
disp('Key was pressed!');

Alternatively, you can use the kbhit function from the MATLAB File Exchange to detect key presses. This function works on Windows and Linux systems:

main.m
disp('Press any key');
while ~kbhit % Wait for key press
end
disp('Key was pressed!');

Note that the kbhit function waits for any key press, not a specific key. If you need to detect a specific key, you can use the getkey function from the same File Exchange submission.
